Printer system having two or more ink cartridges

Abstract

A printer system includes a printer on which color and monochromatic print cartridges are mounted, and a personal computer to output bit map data to the printer. The kinds of these ink cartridges are memorized as status information within a RAM so that the personal computer can detect a cartridge mounted position based on the status information. In the case that the color and/or monochromatic print cartridge is mounted incorrect, the personal computer detects an amount of a difference from a normal mount position to cause print data to shift depending upon the difference, thus creating bit map data.

What is claimed is: 
     
       1. A printer system comprising: a carrier having a first position in which a first ink cartridge is held and a second position in which a second ink cartridge is held;   an incorrect mounting detecting means for detecting that a least one of the said first ink cartridge and said second ink cartridge is held in an incorrect position; and   a control means for controlling print operation depending upon detection by said detecting means,   said control means including a difference detecting means for detecting a difference between a normal mounting position and an incorrectly mounted position of the at least one of said first ink cartridge and said second ink cartridge, and a correcting means for correcting a print position depending upon the difference,   said correcting means including a print data correcting means for correcting print data,   said print data correcting means including a data shift means for causing the print data to shift in position,   said incorrect mounting detecting means including a first detecting means for detecting first incorrect mounting wherein said first ink cartridge is held in said second position, and a second detecting means for detecting second incorrect mounting wherein said second ink cartridge is held in said first position, and   said data shift means including a first shift means to cause the print data to shift in a first direction when the first incorrect mounting is detected by said first detecting means, and a second shift means to cause the print data to shift in the second direction when the second incorrect mounting is detected by second detecting means.   
     
     
       2. A printer system comprising: a carrier having a first position in which a first ink cartridge is held and a second position in which a second ink cartridge is held;   an incorrect mounting detecting means for detecting that at least one of said first ink cartridge and said second ink cartridge is held in an incorrect position;   a control means for controlling print operation depending upon detection by said detecting means,   said control means including a difference detecting means for detecting a difference between a normal mounting position and an incorrectly mounted position of the at least one of said first ink cartridge and said second ink cartridge, and a correcting means for correcting for a print position depending upon the difference,   said correcting means including a position correcting means for correcting for a print start position depending upon the difference, and   said incorrect mounting detecting means including a first detecting means for detecting first incorrect mounting wherein said first ink cartridge is held in said second position, and a second detecting means for detecting second incorrect mounting wherein said second ink cartridge is held in said first position, and   said position correcting means including a first position changing means for changing the print start position in a first direction when the first incorrect mounting is detected by said first detecting means, and a second position changing means for changing the print start position in a second direction when the second incorrect mounting is detected by said second detecting means.   
     
     
       3. A printer system according to claim 2, wherein said first position changing means and said second position changing means respectively include address changing means.
